Chosen Solution

Not really a question; more like asking for confirmation of my assessment! The Wi-Fi option is grayed out on the iPad. Bluetooth is switchable, but cannot locate devices. I’ve reset the network settings, all settings, and done a full restore of the iPad, and so I’m fairly certain it’s not software. My assumption is that it’s the Wi-Fi antenna and not the chip itself because I still have a MAC address for both Wi-Fi and Bluetooth. Also, there’s no physical damage to the unit; everything looks like it’s in great shape. Do you think I’m right? Thanks for your help in advance!

Antenna would usually just give you a weak signal, it’s usually the chip that greys out the option

I think you should first try replacing the antenna and if that doesn’t work then the chip because the wifi antenna is rely cheap so it’s worth a shot.iPad 3 and 4 Wi-Fi/Bluetooth Antenna
